Systemic Review of Intrusion Prevention Systems (IPS)

The ever-evolving landscape of digital communications has sporadically interconnected people in various corners of the earth, ensuring optimal delivery of information. This rise in networking also led to increasing threats on network intrusion; leading to security incidents, data leaks, phishing attacks, etc. Thus, there is a need for intrusion detection and preventive systems to be actively deployed on networks for safe utilization of the numerous advantages of network systems. Intrusion detection systems when deployed actively monitors all incoming and outgoing network activities, scanning for improper network anomalies and when incongruities are detected, it sends alarms to network administrators. This type of intrusion system acts more like a passive monitoring system. An Intrusion Preventive System on the other hand, functions more as an Intrusion Detection System; however, with the added advantage that it prevents such anomalies from occurring in the first instance. This study gives an in-depth review of Intrusion Prevention Systems, detailing their various operations and how they can be deployed on active networks.
